Fluorinated Cannabidiol Derivatives: Enhancement of Activity in Mice Models Predictive of Anxiolytic, Antidepressant and Antipsychotic Effects Aviva Breuer, Christeene G. Haj, Manoela V. Fogaça, Felipe V. Gomes, Nicole Rodrigues Silva, João Francisco Pedrazzi, Elaine A. Del Bel, Jaime C. Hallak, José A. Crippa, Antonio W. Zuardi, Raphael Mechoulam, Francisco S. Guimarães PLOS One, 2016, 11, (7), e0158779, 1-19. Doi : 10.1371/journal.pone.0158779 Abstract Cannabidiol (CBD) is a major Cannabis sativa constituent, which does not cause the typical marijuana psychoactivity.

Frank, Tallan Black, Pramodkumar D. Jadhav, Larry A. Holbrook & Robert B. Laprairie Scientific Reports, www.nature.com, 2020, 10, 20405, 1-13. Doi : 10.1038/s41598-020-77175-y The Cannabis sativa plant contains more than 120 cannabinoids. With the exceptions of Δ9-tetrahydro-cannabinol (Δ9-THC) and cannabidiol (CBD), comparatively little is known about the pharmacology of the less-abundant plant-derived (phyto) cannabinoids. The best-studied transducers of cannabinoid-dependent effects are type 1 and type 2 cannabinoid receptors (CB1R, CB2R). Partial agonism of CB1R by Δ9-THC is [...]

The Impact of Cannabidiol on Human Brain Function : A Systematic Review Albert Batalla, Julian Bos, Amber Postma and Matthijs G. Bossong Frontiers in Pharmacology, January 2021 | Volume 11 | Article 618184, 1-15. doi : 10.3389/fphar.2020.618184 Background : Accumulating evidence suggests that the non-intoxicating cannabinoid compound cannabidiol (CBD) may have antipsychotic and anxiolytic properties, and thus may be a promising new agent in the treatment of psychotic and anxiety disorders. However, the neurobiological substrates underlying the potential therapeutic effects of CBD are still unclear. The aim of this systematic review is to provide a detailed and up-todate systematic literature overview of neuroimaging studies [...]

Ortiz, Praveen Kulkarni, Clare T. Johnson, Heather B. Bradshaw, Bruce S. Cushing, Ai‑Ling Li, Andrea G. Hohmann and Craig F. Ferris Journal of Translationnal Medicine, 2021, 19, 220, 1-16. Doi : 10.1186/s12967-021-02891-6 Abstract Background : The phytocannabinoid cannabidiol (CBD) exhibits anxiolytic activity and has been promoted as a potential treatment for post-traumatic stress disorders. How does CBD interact with the brain to alter behavior? We hypothesized that CBD would produce a dose-dependent reduction in brain activity and functional coupling in [...]
Lire la suiteTroubles anxieux : le CBD peut soulager les symptômes Kalapa Clinic, Barcelone, Espagne By Gesa|30/06/2020 La peur est une réaction naturelle à certaines situations et à certains événements. Elle remplit à la fois une fonction d’avertissement et de protection. Lors d’un trouble anxieux, cependant, elle développe une dynamique propre qui est très stressante pour les personnes concernées. Diverses études et rapports d’expérience indiquent que le cannabinoïde non-psychoactif cannabidiol (CBD) peut soulager leurs symptômes. En Allemagne, le trouble anxieux est la maladie mentale la plus courante, devançant même la dépression. Environ 12 millions de personnes sont touchées, les femmes plus souvent que les hommes (1).

Publié le 12 mai 2020 NEWSWEED.fr , Par Aurélien BERNARD https://www.newsweed.fr/comment-terpenes-affectent-effets-variete-cannabis/ Lorsqu’on entend le mot terpène, la première idée qui vient à l’esprit est l’odeur d’une plante. La recherche scientifique a pourtant montré que les terpènes remplissent plus qu’une unique fonction sensorielle. Les terpènes produisent ainsi des effets spécifiques sur le corps, qu’ils soient anti-inflammatoires, antibactériens, relaxants ou anxiolytiques. C’est d’ailleurs aussi pour cette raison que certaines variétés procurent un sentiment de calme et de bien-être, alors que d’autres favorisent l’énergie. Les terpènes s’insèrent ainsi complètement dans l’effet d’entourage, qui suppose que les composants [...]
